SYSTEM SCALE ESTIMATION SYSTEM, SYSTEM SCALE ESTIMATION METHOD, AND SYSTEM SCALE ESTIMATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a system scale estimation system, a system scale estimation method, and a system scale estimation program, for accurately and efficiently computing the scale of a system to be developed.;SOLUTION: An FP number estimate formula parameter generation processing section 23 of an arithmetic processing section 20 acquires subject result data stored in a subject result data storage section 21 to total the data for respective parameters (the number of screen, form, internal file, and other system linkage). Then, the FP number estimate formula parameter generation processing section 23 computes expression formulae for respective functions (EI, EO, EQ, ILF, EIF) using respective parameters totaled, then computes coefficients (A, B, C, D) of the parameters using a statistical average percentage of functions, and stores them in an estimate formula parameter storage section 24. The arithmetic processing section 20 having acquired respective parameters of an estimate target system, uses the coefficients to compute an FP number.;COPYRIGHT: (C)2008,JPO&INPIT
